CLEANING DEVICE FOR FALSE TEETH.

Application filed December 5, 1927. Serial No. 237,828.

My present invention, in its broad aspect, has reference to improvements in cleaning devices of the type having a receptacle for receiving the object to be cleansed and lined,

with bristles, and having a cover carrying a rotatable brush element for agitating and scouring the object in the receptacle. More particularly it is my purpose to provide a device of this character which is especially adapted for use in cleaning false teeth or dental plates.

Ordinarily false teeth or dental plates must be scrubbed at least once a day to insure cleanliness and prevent the formation of toxic substances in the crevasses thereof. This is a tedious operation when done properly with an ordinary hand brush, and my device is designed to accomplish the purpose quickly, thoroughly, and conveniently without the use 2 of highly intricate mechanism or apparatus which cannot be kept in a thoroughly sanitary condition.

Other and equally important advanta es of my invention may be briefly defined as 01- lows; first, I provide a wholly watertight receptacle and cover thereby preventing splashing or leakage of the contents of my device; second, I provide a resiliently mounted plate to yieldingly press a set of false teeth in the receptacle to cause the bristles to enter all crevasses and to give the necessary scouring action, as well as to accommodate false teeth or other objects of different sizes; third, I provide a container, which when closed, will wholly surround the object to be cleaned with bristles, and; fourth, I attain all of the above and other objects with a simple, inexpensive and durable device.

Other and equally important objects and advantages will become apparent as the description of my invention proceeds, but while I have in the present instance defined for the sake of illustration a process or method of a certain specific nature, it will be understood 4 that I'do not desire to limit myself except as may be indicated by the scope of the claims appended hereto and forming a part of this specification.

In the drawin s wherein I have illustrated the preferred em odiment of my invention Figure 1 is a sectional side elevation of my device, and; Figure 2 is a top plan view thereof.

In the drawing wherein like characters of reference are used to designate like or simils? parts throughout the several views there- I o The numeral (1) designates a receptacle which is preferably cylindrical in form and made out of sheet metal with watertight seams. The receptacle 1) is lined at its sides and bottom with a brus or bristle device including backing material (2) in which the bristles (3) are set. The backing may be either permanently or removably attached to the walls of the receptacle and the bristles extend toward the center thus providing a chamber (4) surrounded by bristles. A set of false teeth (not shown) is deposited in the chamber (4:) when it is desired to cleanse them.

My receptacle is provided with a cover (5) hinged at (6) thereto and provided with a seal (7) to form a water tight closure when the device is in use. A latch formed of cooperating members (8) and (.8") is provided to hold the cover closed. The receptacle is provided with a resilient base element (9) to prevent scratching or the like of a table, and a suitable handle (10) Rotatably and slidably mounted centrally of the cover is a shaft (11) having a bushing (12) and an operating handle (13). The shaft extends out from the under side of the cover and carries a plate (14), on which is mounted the backing (15) and bristles (16). A spring (17) holds the shaft in the position shown in Figure 1, but the plate may be pushed in toward the cover against the resistance of the spring (17) to accommodate sets of false teeth of different sizes and the like. A water proof gasket (18) is provided around the shaft to prevent eakage.

In operation a set of false teeth is placed in cavity (4) of the receptacle (1) and the 95 cover (5) closed down thereby bringing the bristles (16) to bear against the teeth. The plate being free to move toward the cover against the ressure exerted by the spring it is held agalnst the teeth thus forcing the bristles into each cavity thereof to thoroughly cleanse the same. The plate (14) is then rotated by the handle (13) to thoroughly scour the teeth, and if desired a suitable cleansing compound can first be placed in the receptacle. The device is handy, compact and simple in construction and can be easily kept in a thoroughly sanitary condition.

While in the foregoing there has been illustrated in the drawings and described in the 110 specification such combinationand arrangement of elements as constitute the preferred embodiments of my invention, it is nevertheless desired to emphasize the fact that interpretation of the invention should only be conclusive when made in the light of the subfronr the cover, a spring for urging the plate away from the cover, and bristles carried by the plate and extending into the receptacle.

. 2. A device of the character described comprising a hollow receptacle, bristles carried on the inner walls of the receptacle, a, cover for the receptacle, a longitudinally movable and rotatable shaft carried by the cover, a

handle on the shaft, a plate on theshaft and extending into the'receptacle, a spring about the shaft for urging the plate away from the cover, and bristles carried by the plate.

3. A device of the character described comprising a hollow watertight receptacle, bris tles wholly covering the inner surfaces'of the receptacle, a cover for the receptacle, means for sealing the cover when it is closed, a rotatable and longitudinally movable shaft carried by. the cover, a spring exerting its force against longitudinal movement of the shaft, 21 plate on the shaft and extending into the receptacle, and bristles wholly covering that surface of the plate presented toward the receptacle.

In testimony whereof, I afiix my signature hereunto.
